Yeah, I’m with you. 2001 and DDR… there’s something else going on with the failure to boot. I don’t think the Pentium 3 ever supported DDR, so this is probably a Pentium 4. If truly a model released in 2001, it would be Willamette, but that required RDRAM. DDR support was introduced with Northwood in 2002. On the other hand, it could be the P4 that was new in 2004, Prescott, and the 2001 statement comes from the first year the P4 was released.
A couple others, if MPD looks appealing, are Navidrome and Mopidy.
